כִּ֤י אֹ֣זֶן שָׁ֭מְעָה וַֽתְּאַשְּׁרֵ֑נִי וְעַ֥יִן רָ֝אֲתָ֗ה וַתְּעִידֵֽנִי׃
sapagkat ang taingang nakarinig sa akin ay pumupuri sa akin, at ang matang nakakita sa akin ay nagpapatotoo para sa akin;

ועפרון..באזני בני חת, in a loud voice, making sure they could all hear him. In this verse the Torah emphasises the aural aspect of the negotiations, whereas in verse 18, at the conclusion of the transaction the visible aspect, לעיני בני חת is stressed, as at that point eye-witnesses were more important. We find such a sequence of aural perception and visual perception also in Job 29,11 כי אזן שמעה ותאשרני ועין ראתה ותעידני, “for the ear that heard acclaimed me, and the eyes that saw were my witness.”
